Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed August 21,1905. Serial No. 275,027.

To all whom it may concern:

Be it known that I, RANDALL M. PATTER- SON, a citizen of the United States, residing at Veatherford, in the county of Custer and Territory of Oklahoma, have invented a certain new and useful Acetylene-Gas Machine, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to acetylene-gas' machines, and particularly to that class of machines known as carbid-feed generators, the primary object of the invention being to provide a simple, economical, and re liable acetylene-gas generator which will fulfil the requirements of insurance companies in point of safety.

One of the main objects of the invention is i to provide means for intermittently discharging a predetermined amount of carbid into the water, said means being entirely automatic in action and the amount or charge of carbid being accurately measured previous to the same being deposited in the water.

A further object of the invention is to provide a machine of such construction that the several parts thereof may be easily disasseciated for cleaning, repairing, and refilling or charging.

\Vith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel constructions, combination, and arrangement of parts, as herein fully described, illustrated, and claimed.

In the accompanying drawings, formin part of this application, Figure 1 is a vertica sectional view of an acetylenegas machine embodying the present invention. Fig. 2 is an enlarged vertical sectional view of the carbid-holder, showing the carbid measuring and discharging mechanism. Fig. 3 is a bottom plan view of the carbid-holder, showing the carbid-valve and the operating mechanism therefor.

Like reference-numerals designate corresponding parts in all figures of the drawings.

The generator contemplated in this inven tion comprises an outer can or vessel 1 of suitable height and diameter, according to the capacity of the machine, and 2 represents the inner can or shell, which extends from a point near the top of the outer can downward until it meets and connects with an annular floor 3, the latter, together with the in- 1 ner can, being supported on brackets 1, se-

cured to the inside of the outer can, as shown. Between the outer and inner cans 1 and 2 an annular water-seal space is left, in which is received the lower portion of the gas-bell 5, the latter fitting loosely around the inner can and being closed at the top, where it is provided with a vent-cock 6, which is normally closed. The outer can 1 is provided with a slanting bottom 7, and a draw-off cock 8 is located in the side of the can adjacent to the lowest portion of the slanting bottom to provide for drawing off the water from the can preparatory to replenishing the same.

The carbid-holder 9 is removably mounted in the upper portion of the inner can 2, being supported on brackets 10, secured to the inner can, as shown, and is thus adapted to be taken out of the machine after the as-bell has been lifted off, thus greatly facilitating the recharging of the machine. This carbidholder is provided with a flanged top or cover 11 and has an invertedcone-shaped bottom 12, with a central discharge-opening 13 disposed above the water-level in the inner can. Beneath the cone-shaped bottom 12 is a horizontal bottom plate 14, to the bottom of which is secured a measuring cup or chamber 15, adapted to contain a certain amount of carbid sufficient when deposited in the water to generate gas enough to nearly fill the bell 5, causing the latter to rise. It will be noted that the discharge-opening is somewhat smaller than the measuring-cup to prevent the carbid from congesting in the discharge-orifice.

The carbid at the point of discharge is loosened up by means of an agitator consisting of a rod or stem 16, having a carbid-lifting crook at its lower end, while the upper end thereof extends throu holder to be acted upon and depressed by the gas-bell as the latter descends just before a new charge of carbid is to be dropped into the water. The rod or stem 16 passes through a tube or guide 17, supported centrally within the carbid-holder by means of brackets 18, and said rod or stem is normally pressed upward and upheld by means of a spring 19, which encircles the stem within the tube 17 and bears beneath a pin or shoulder 2-0 on the rod or stem.

h the top of the- Extending under the cup or measuring-receptacle 15 is a valve or plate 21, which closes the lower end of said cup and retains the carbid therein preparatory to its discharge. The valve or plate 21 is carried by an arm or brace 22, which at its outer end is mounted on the lower end of a vertically-adjustable rod or stem 23. This rod passes upward through a tubular guide 24, supported by brackets 25, and the upper end of such rod is threaded and provided with a nut 26, which bears on the upper end of the tubular guide and renders the rod 23 adjustable up or down for the purpose of bringing the valve or plate 21 into proper relation to the discharge-orifice of the cup 15. Said rod or stem 23 also forms a pivot or journal about which the valve or plate 21 is adapted to turn for covering and uncovering the cup 15.

The operating mechanism for the valve or plate 21 comprises a rockshaft 27, mounted in bearings 28 on the bottom plate 14. This shaft is provided at one end with a crankarm 29, to which is attached one end of a chain '30, the other end of which is connected to the valve-plate 21. At the opposite end the shaft 27 has another crank-arm 31, to which is connected the lower end of a rod 32, the latter extending upward through one or more guides 33 and above the carbidholder, so as to be depressed by the gas-bell as the latter descends. Thus when the bell approaches the lower limit of its movement it depresses the rod 32, rocks the shaft 27, and moves the valve from under the cup 15, allowing a charge of carbid to fall into the water. As soon as the gas is generated the bell rises again, releasing the valve-operating connections, whereupon the valve is returned to its closed position by means of a retracting-spring 34, one end of which is connected to the valve and the other end to the body of the carbid-holder.

35 designates a gas-receiving pipe extending vertically within the inner can or shell to a point near the top of the latter. The lower end of this pipe is coupled to a horizontal pipe 36, one end of which extends into a condensation-box 37, secured to one side of the outer can 1 and provided with a nipple 38 for the attachment of the servicepipe for conducting the gas to the burners. Said box is also provided with a drain-cock 39 to draw off the residuum. The other end of the pipe 36 passes out through the side of the can 1 and has a vertical extension 40, supported by one or more brackets 41 on the can and reaching to a suitable point above the top of the can, where it is provided with a safety valve or cock 42, the latter having a crank-arm 43 projecting therefrom into the path of the gas-bell, so that in case there is an excess of gas within the bell the latter will in its upward movement come in contact I with the crank-arm 43, causing the latter to open the valve or cook 42 and liberate the gas, thus preventing the bell from being lifted out of the water seal and displaced.

Having described the invention, I claim asnew 1. In an acetylene-gas machine, the combination of a can, a gas-bell movable up and down therein, and a removable carbid-holder in said can carrying a measuring-cup open at the bottom, and a pivoted and swinging plate-valve also carried by said holder and movable edgewise across the bottom of said cup for closing the same, and valve-operating means carried by and removable with the carbid-holder and embodying a rod having connection with the valve and extending upward alongside the carbid-holder and arranged to be operated by the gas-bell.
